    • A paper web is continuously reeled into reels around rotating reeling cores. Before a change of reel a new empty reeling core (5) is brought to the change station into change connection with the paper web (W) going to the old reel (R), and when the old reel (R) is full, the web is changed in a change event to travel to the periphery of the new reeling core (5) and a primary reeling is started where the web is guided to form a rell around the reeling core (5) through a reeling nip (N1) between the loop of an endless supporting member (1) and the reeling core. From the primary reeling a change is made to secondary reeling, where a portion of the supporting member (1) carrying the web brings the web to the reel, and the web moves over to the reel in a reeling nip (N) between said portion and the outer periphery of the reel. During the secondary reeling at least in some stage the reeling core (5) is transferred in relation to the loop of the supporting member (1) according to the increase of the diameter of the reel (R) in such a manner that the position of said reeling nip (N) moves forward on the web-carrying portion of the endless supporting member (1) in the travel direction of said portion. A first guide roll (2) of the web-carrying portion of the loop of the endless supporting member (1) is transferred in the direction of the periphery of the reeling core (5) so that the distance of the reeling nip (N1) located between the reeling core (5) and the loop of the supporting member (1) from the first guide roll (2) changes in the primary reeling.

    • An apparatus serving for winding up a material web in rolls on roll shafts. The apparatus is comprising two roll carriages, each having supporting structures for supporting the ends of a roll shaft (1; 2) and also rotating means for rotating said shaft during operation, means for conveying each carriage to-and-fro between a start position where the winding-up of a roll (3) of web (13) on an empty shaft (1) is started, and a finish position where the winding-up of the roll is finished, a first pressure roller (4) being displaceable between a first position where the roller is supporting the web at a distance from an empty shaft (1) on a carriage being in start position and a second position where the roller is pressing the web against said shaft, a second pressure roller (5) displaceable between a start position where the roller is free of the web (13) and other positions where the roller is engaging the periphery of a web roll partly or completely wound-up, a cutting knife (18), which is placed in an area between the first and second pressure rollers (4; 5) and is displaceable between a first position at a distance from the web and a second position where the knife has cut through the web, and means for, at roll exchanging, simultaneously or immediately after each other, displacing the first pressure (4) roller and the cutting knife (18) from the first to the second position. The apparatus has a simple construction and is able to easily and safety start the winding-up of the web on a new roll shaft at roll shifting. The apparatus also can be used for cutting off a free length of the web for rejecting this length.

    • Bei einer Vorrichtung (26) zum Aufwickeln einer Materialbahn, insbesondere Papieroder Kartonbahn, auf einen Tambour (28), ist der Tambour in einer Primärwickelphase durch Primärhebel geführt, wobei er anschließend von den Primärhebeln an Sekundärhebel (30) übergeben wird, um in einer Sekundärwickelphase weiter bewickelt zu werden. Die Materialbahn wird über eine Tragtrommel geführt, wobei zwischen dem Tambour bzw. dem darauf zu bildenden Wickel und der Tragtrommel ein Wickelspalt gebildet ist und der Tambour zur Erzeugung einer Linienkraft in dem Wickelspalt über einen den Primärhebeln zugeordneten Tambourhalter oder dergleichen bzw. über die Sekundärhebel an die Tragtrommel anpressbar ist. Die mittels einer Steuereinrichtung (38) ansteuerbaren Sekundärhebel (30) sind zumindest in der Phase, in der sie an den neu gewickelten Tambour angelegt werden, über wenigstens ein zwischen der Steuereinrichtung und den Sekundärhebeln vorgesehenes Kraft- oder Druckbegrenzungselement (40) ansteuerbar.
    • 该装置具有一个具有用于初级绕组相的初级杠杆的鼓形件(28)和用于次级卷绕相位的次级杆(30)。 次级杆具有控制装置(38),并且至少在一个阶段期间,它们被移动成与新缠绕的鼓形物接触,它们由位于次级杆和装置之间的压力或力限制器元件控制。 该元件具有直接控制的压力限制阀(40),其具有密封锥(42),当已经达到调节压力时,其被提升离开座(46)。 该元件用作用于装载辅助杆的液压/气动缸(36)的调节元件。
